The human waste is growing faster than the increasing global population. By the end of this century, the production of waste is expected to peak at three-times today’s current generation rate. Urbanization “Cities” is supposed to be the best bet we have to meet global poverty reduction targets through feedbacks on wealth, culture, and innovation. However, there are many severe negative impacts from urbanization on environmental conditions in particular aquatic and ecological qualities as well as the global biodiversity. Urbanization is taking place and expanding so rapid that it is, at the same time, bringing with it huge shares of the world’s GHG “Green House Gas” emissions, increasing decline in biodiversity, lots and fast generation of amounts of solid waste.
If we don’t urgently invest and put huge efforts in management of our waste and mitigating their impacts on water, eco-systems and biodiversity future generations will be forced to spend their lifetime in environmental and ecological bankruptcy resulted from our “production-consumption” civilization. Most of the time for future generation, in particular in the next century, have to be spent not only for searching about food but, also, for finding non-toxic and healthy food. The priorities of the next century will shift towards fighting against increasing degradation of environment and water resources; putting more resources, energy and efforts in waste-treatment, fighting against diseases, spending much of their resources on medication and protection from pollution and waste.
